Interstate 78 (I-78) is a part of the Interstate Highway System that runs from Union Township, Pennsylvania, to New York City. The portion of I-78 within the U.S. state of New York is just 1 mile (1.6 km) long as it crosses the Hudson River from New Jersey via the Holland Tunnel and ends at the tunnel plaza in Lower Manhattan. Therefore the entire route is maintained by the Port Authority of New York and New Jersey. However, a much longer route was once planned, heading east via the Williamsburg Bridge to the John F. Kennedy International Airport and then north over the Throgs Neck Bridge to I-95 in the Bronx. The parts of this that were built are now New York State Route 878 and Interstate 295.


Route description

The Holland Tunnel consists of two one-way two-lane tunnels. The entrance plaza to the westbound tunnel is a rectangular block bounded by Broome, Varick, Watts, and Hudson Streets, with four entrances feeding into the tunnel from all directions, including one from Canal Street. The westbound portal is to the north, just south of Dominick Street. The exit plaza is in the square double block that originally housed the New York Central Railroad's St. John's Park Terminal, bounded by Laight, Varick, Beach, and Hudson Streets. Traffic leaves the tunnel at a portal at the southeast corner of Canal and Hudson Streets, and heads southeast along the south line of Canal Street and south along the west line of Warick Street to the northeast corner of the plaza. Five exits, numbered 1 to 5, can be taken from the almost-circular roadway, one to each corner and one to the middle of the east side (Varick Street). A pedestrian overpass crosses the entrance to the plaza and exit 5 at the northeast corner, since the entrance from the tunnel cuts Laight Street.[2]


Auxiliary Routes

There are four auxiliary routes of I-78, all entering New York, and none connecting with I-78 (due to unbuilt parts of I-78, I-278, and I-478). Interstate 278 begins in Linden, New Jersey and passes through all five boroughs to end at the Bruckner Interchange in the Bronx; it was proposed to continue west to I-78 in Springfield. The original alignment of I-278 was to end at I-95 in the northeastern Bronx, and is now partially I-895. Interstate 478 is currently the Brooklyn Battery Tunnel and approaches, connecting I-278 in Brooklyn with the Battery in Manhattan; it was once planned to continue north along the unbuilt Westway to I-78 at the Holland Tunnel. I-478 was originally assigned to the Manhattan Bridge and a branch of the Lower Manhattan Expressway, connecting I-78 in Manhattan with I-278 in Brooklyn. Interstate 678 runs from the John F. Kennedy International Airport in Queens north to the Bruckner Interchange; its original planned south end was at I-278 in northwestern Queens. Interstate 878, signed as part of State Route 878, is a short east–west route crossing I-678 at the JFK Airport; it was originally planned to continue west across Brooklyn to I-278 in the southwest part of the borough. The original I-878 is now I-278 east of I-895, and connected I-278 with I-78, I-95, and I-678.


1955 Yellow Book plan for Interstates in New York City, including the entire route that would become I-78 except for the Throgs Neck Expressway

When the Interstate numbering was finalized in the late 1950s, the Harrisburg-New York City route, I-78, was assigned to several proposed roads in New York City. It would leave the Holland Tunnel onto the Lower Manhattan Expressway, crossing the East River on the Williamsburg Bridge and following the Bushwick Expressway across Brooklyn to near the John F. Kennedy International Airport. There it would follow the Nassau Expressway along the north boundary of the airport and turn north along the Clearview Expressway through Queens, crossing the East River again on the Throgs Neck Bridge into the Bronx. Finally, I-78 would split into two branches, one heading west along the Cross-Bronx Expressway to the Bruckner Interchange and the other heading northwest along the Throgs Neck Expressway to the Bruckner Expressway near the south end of the New England Thruway. Other Interstates junctioned would be Interstate 478 (Manhattan Bridge) in Manhattan, Interstate 278 (Brooklyn-Queens Expressway) in Brooklyn, Interstate 495 (Long Island Expressway) in Queens, and Interstates 95 (Cross-Bronx and Bruckner Expressways), 678 (Whitestone Bridge), and 878 (Bruckner Expressway) in the Bronx.[3][4]

When the Throgs Neck Bridge and approaches opened in early 1961, it was signed as I-78. The lack of expressway names on the signs, as specified by federal standards, caused confusion among drivers who knew the highways by their names.[5][6] The Clearview Expressway was completed to its present extent in mid-1963,[7] and a short eastbound-only piece of the Nassau Expressway opened in 1971.[8] Other than the preexisting Holland Tunnel and Williamsburg Bridge, no other portions of I-78 were built.

Although the Lower Manhattan Expressway caused the most controversy, the first to be canceled was the Bushwick Expressway, which would have linked the Williamsburg Bridge to the Nassau Expressway via the Bushwick Avenue and Conduit Boulevard corridor. At the urging of Mayor John V. Lindsay, the Cross Brooklyn Expressway, which would connect to the Verrazano-Narrows Bridge, and not provide a link in I-78, was substituted for the Bushwick Expressway in 1967, in order to reduce traffic into Manhattan.[9][10] While campaigning for re-election in 1969, Mayor Lindsay cancelled plans for the Lower Manhattan and Cross Brooklyn Expressways, citing lack of community support.[11][12] All three unbuilt expressways along the path of I-78 were deleted at the state level by Governor Nelson Rockefeller in March 1971.[13]

Effective January 1, 1970, the New York State Department of Transportation truncated the east end of I-78 to the east end of the Williamsburg Bridge at I-278 in Brooklyn. The Clearview and Throgs Neck Expressways, as well as the eastern part of the Cross-Bronx Expressway, became Interstate 295, and the Nassau Expressway became Interstate 878,[14] though it was still shown as I-78 on maps[15] and signs until 1989. I-878 was also assigned to the unbuilt Cross Brooklyn Expressway, for a total of 15.6 miles (25.1 km) between the Verrazano-Narrows Bridge and the John F. Kennedy International Airport.[16][17]

Exit list

Note: These exits are all eastbound-only, numbered sequentially as traffic heads counterclockwise around the tunnel's exit plaza; the westbound entrance plaza is several blocks to the north, and has direct entrances from Hudson Street, Canal Street, Watts Street, and Varick Street.

The entire route is in New York City, Manhattan.
